Infineon公司的ICE5QRxx80BG是第五代准谐振CoolSET™功率集成电路,最适合串联配置的离线开关电源,在单个封装内有两个单独的芯片:控制器芯片和HV MOSFET芯片.器件通过专有新颖的准谐振运作,降低数字频率,从而得到更低的EMI和更高的效率.增强的有源突发模式使得待机功率范围更加灵活机动.器件的工作电源更宽(10~25.5V),并有更低的功耗.器件的众多保护功能包括鲁棒的线电压包括(输入OVP和降压),以支持故障状态下电源系统的保护.器件集成了800V雪崩电压的CoolMOS™,待机功耗小于100mW,内置了数字软起动和逐个周期的峰值电流限制.所有这些都使得CoolSET™ (ICE5QRxx80BG)系列在准谐振反激转换器市场中是非常优秀的功率器件.主要用在家用电器/白色家电,TV,PC和服务器,蓝光播放器,机顶盒和LCD/LED监视器的辅助电源.中电网为您整理如下详细资料,本文介绍了CE5QRxx80BG产品亮点和特性,框图和应用电路,42 W 12 V 5 V开关电源(SMPS)演示板5QR0680BG_42W1指标,电路图,材料清单和PCB设计图.

The Quasi-Resonant CoolSET™- (ICE5QRxx80BG) is the 5th generation of Quasi-Resonant integrated power IC optimized for off-line switch power supply in cascode configuration. It is housed in single package with 2 separate chips; one is controller chip and other is HV MOSFET chips. The IC can achieve lower EMI and higher efficiency with improved digital frequency reduction through the proprietary novel Quasi-Resonant operation. The enhanced Active Burst Mode enables flexibility in standby power range selection. The product has a wide operation range (10 ~ 25.5 V) of IC power supply and lower power consumption. The numerous protection functions including the robust..
